ATTACHMENT FOR LATERAL CGNVEYEBS.

Specification of Letters Patent.

Application filed February 10, 1913. Serial No. 747,572.

To all whom it may concern:

Be it known that I, ARTHUR C. VAN HOU- WELING, a citizen of the United States, and resident of Pella, in the county of Marion and State of Iowa, have invented a certain new and useful Attachment for Lateral Conveyers, of which the following is a specification. I

The object of my invention is to provide an attachment for lateral conveyers of simple, durable and inexpensive construction, aving parts so made and arranged that in one position of the attachment a lateral conveyer may swing in a horizontal plane while in another position of said attachment the conveyer may be locked against horizontal swinging movement. I My invention consists in certain details, in the construction, combination and "arrangement of the various parts of the device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 shows aside elevation of a part of a threshing machine and lateral conveyor provided with an attachment, embodying my invention. Fig. 2 shows a detail view of a portion of the mechanism for locking the conveyor against swingin movement in a horizontal plane. Fig. 3 siliows a detail,

sectional View taken on the line 33 of Fig 2. Fig. 4 shows a detail View of the mechanism shown in Fig. 2 taken at right angles to the view in Fig. 2, and Fig. 5 shows a detail view of the ratchet wheel which forms a part of my device.

In the accompanying drawings, I have used the reference numeral to indicate that portion of the threshing machine shown. Suitably mounted on the main body of the threshing machine is a frame 11 of a band cutter and feeder which may be of ordinary construction. I preferably mount on my machine two lateral conveyor-s12 which maybe mounted in the manner and by the means described in my application for patent on a lateral conveyer for thresha ing machines, Serial Number 624,297, filed on May 1, 1911. I preferably employ mechanism 13 also described in my said prior application for elevating and lowering each lateral conveyer. For firmly supporting the lateral conveyor frames against movement in a horizontal plane, when desired, and for permitting said movement, when desired,

I have provided the following means which may be securedor released by an operator elther at the outer end of the side conveyer or upon the ground near the pivoted end of said conveyer. A similar device is used for each lateral conveyer and I will describe the device therefore fully as applied to one of said conveyers.

Extending laterally from the frame of one of the conveyors 12 is a bracket 1 1to which is pivotally connected tired or tube 15. I provide on the frame of the band cutter a laterally extending bracket 16, shown in F 1. Pivotally secured thereto is a rod 17'. Detachably mounted on the end of the tube or rod is a hollow clutch or tube 18. The walls of the clutch 18 are slotted at 19. On one side of the clutch 18, adjacent to the slot 19 I provide parallel opposite disk shaped lugs 20-and 21. One end of the rod 17 is received in the clutch 18, as shown in Figs. 2, 3 and 4. It is obvious that so long as the rod 17 may slide freely in the clutch 18, the lateral conveyer 12 may swing freelyin a horizontal plane and that when said rod 17 and said clutch 18 are locked against movement relative to each other, then the lateral movements of the conveyor 12 will be prevented.

Extended through the disks 20 and 21 is a bolt .22 having rotatably mounted thereon a ratchet wheel 23. This ratchet wheel 23 is provided on its side adjacent to the lug 20 with a plurality of spaced lugs 24 illustrated in Figs. 4 and 5. The surface of the bolt or lug 20 adjacent to the ratchet wheel 23 is provided with a plurality of notches or depressions 25 designed to receive and coact with the lugs 24 in certain positions of the movement of the ratchet wheel 23 with relation to said lug 20. Pivotally mounted and fulerumed on the bolt 22 is a. lever 26 which extends in opposite directions "from said bolt 22. Pivoted to one arm of the. lever 26 is a swinging pawl 27 designed to be received in the notches 28 of the ratchet wheel 23 to thereby operate said wheel. A contractible coil spring 29 is secured to the pawl 27 and is detachably secured at its other end to a support 30 on the tube 15 as shown in Figs.

2 and 4. Ropes 31 and 32 are secured to the opposite ends of the lever 26. The rope 32 is extended over a pulley 33 to be accessible to an operator standing on the ground near the bandcutter and feeder and the rope 31 is extended along the conveyer Patented Dec. 9, 1913.

frame to a point near the outer end thereof where it is accessible to an operator at the delivery end of the conveyer. Upon the Clutch 18 is a projecting guard member 34;

When either of the ropes 31 or 32 are pulled, the pawl 27 engages one of the ratchet teeth, thereby moving the ratchet wheel one tooth space. The movement of the lever 26 each time is limited bythe guard device 34.

It will be understood that the clutch 18 and the disk shaped lugs 20 and 21 are of somewhat resilient materiaL- \Vhen the lugs 24 are received in the notches 25, the resiliency of the members 20 and 21 causes them to stand at the limit of their movement away from each other. Assuming that at the beginning of the operatlon of the device the lugs 2a are received within the notches 25 and that either of the ropes 31 or 32 are pulled, then the ratchet wheel will move one tooth space until the lever is stopped by the guard device 34 and the lugs 24 will be pulled out of the notches25 and will engage the outer surface of the lug 20, thereby pressing the lugs 20'and 21 together and frictionally gripping and holding the rod 17 in the.

My device for controlling the horizontal swinging movement of the lateral conveyer is simple and of durable and inexpensive construction. It is easily operated from the stack which is being built or by an operator standing on the ground near the band cutter and feeder.

I claim as my invention:

'1. In a device of the class described, the combination of. a main frame, a, conveyer frame pivoted thereto to swing in a horizontal plane, two rods slidingly connected with each other, one being attached to the main- -frame and the other being attached to the conveyer frame, and means-for gripping said rods together to prevent lateral movements of theconveyer frame and for releasing said rods so that one may freely slide,

within the other, and the conveyer frame may be freely moved laterally. I

2. In a device of the class'described, the

combination of a main frame, a conveyer frame pivoted thereto to swing in a horizon tal plane, two rods slidably connected with each other, one being attached to a main frame at a point spaced apart from the pivotal point of the conveyer frame, the other being attached to the conveyer frame, means for-securing said rods togetheragainst sliding movement 'With relation to each other and means for operating said first means from either end of the conveyer.
